To the OP, what have you got to loose by trying it? You try it, if it does what's advertised then great.. If you don't like it you return the thing and get your money back. Plain and Simple...

Me I'm testing a tune for Terry on my N55 X5, Terry gave it to me Gratis and I get the added power, and it works as advertised. I can dial up or down the power how I see fit, and if I push it up to much of course It may cause damage and who's fault will it be, MINE, not Terry's and definately not BMW's.

I owned a Procede V4 for my 335xi when I had it, and that worked as advertised too... Never had a issue at the dealership (tuner codes or anything) and it definately provided a boost in power.

So I've sampled both major piggy tuners, and they both do what they say there products will do.

To Aidan.... I suggest you try the product before you knock it. It may just surprise you. And like I said to the OP, if it doesn't work for you, return the item, get your money back. Don't believe you wont get your money back, that's your problem. But they are a pretty well known company here in the states.

As for Kloogy's references to lucky charms, or drunk or whatever... I say whatever... Everyons entitled to their own whims, comments and opinions. As long as its not offensive.. I personally don't find it offensive, but then again I am neither a drunk or Irish, so my opinion on the matter, matters not.

Just my .02 cents... Take it or leave it, matters not to me
